I just had my car tuned and I thick my clutch is giving up. I just installed a 12"in Center Force dual friction ( good for 600 hp ) last month.
What do you thing?

 

Very nice numbers, now get some new times and get on the GTO nitrous list. As for your clutch, if it's toast, then think about the Textralia, it's a killer clutch which will handle all you can throw at it.

Very nice numbers man! i think u need a N20 tune..

 

Nice numbers for the mod's you got.

 

Nice numbers, but why is the spray graph so wavey?

 

Is that clutch slip? Thats what I was asking.

 

how many miles are on that new clutch?

 

My guess is it is a mixture issue the A/F ratio seems to have the same erratic pattern

 

That's part of the problem but what's causing that?

Is the car's tune for N/A or nitrous?

What's your timing set at?

What octane gas are you running?

 

bottle pick up problems can lead to surging like that. Are you certain the bottle valve was fully open and the bottle is mounted correctly?

also, performance clutches are supposed to have about 800 miles of regular street driving on them before you really rip on them. I have seen alot of people glaze their clutches because they werent yet seated properly doing dyno pulls or blasting it with nitrous down the strip.

 

I had the car tuned by Jermey Formato on motor first then he did one pull on 150 to see if it would lean out. The bottle was full so I don't think pressure was the problem. The bottle is mounted in the trunk in the right position. I was running 93 oct that day. I do have a 50 psi fuel pressure safety switch but I don't think it drops below 50 psi. He also told me to run race fuel when spraying and that the 50 psi switch would not cause a problem. The clutch has 1000 miles on it.
